A piston pump is a type of positive displacement pump where the high-pressure seal reciprocates with the piston. Piston pumps can be used to move liquids or compress gases. They can operate over a wide range of pressures. High pressure operation can be achieved without a strong effect on flow rate. Piston pumps can also deal with viscous media and media containing solid particles. This pump type functions through a piston cup, oscillation mechanism where down-strokes cause pressure differentials, filling of pump chambers, where up-stroke forces the pump fluid out for use. Piston pumps are often used in scenarios requiring high, consistent pressure and in water irrigation or delivery systems.

Dongkai is a leading China Chemical Dosing Pumps manufacturers, suppliers and exporter. A chemical dosing system is a facility for automated injection of reagents into a wastewater network for the control of septicity and odour emissions. These systems are typically used at pump stations, sewer manholes, and rising mains. However, they can be installed any place where odour containment is required.

Dongkai is a leading China Ammonia dispensing pump manufacturers. Ammonia dispensing pump, which are reciprocating positive displacement pumps, provide the greatest possible metering accuracy. They set the standard for safety, reliability and efficiency, especially when it comes to pumping supercritical fluids.

Dongkai quality Safety Relief Valve back Pressure Valve help to relieve excess pressure on the pump system or maintain pressure at a setted point. Safely relief valve is installed on the outlet pipeline of metering pump. When the system pressure becomes abnormal, safety relief valve protects metering pump from any damages. Back pressure valve shall be installed at the outlet of metering pump in order to reduce siphon and excess feeding, and ensure the metering accuracy of metering pump is not affected. When dosing point is lower than the outlet of metering. Each Valve is diaphragm type with 2-port design, which can be used both as safety relief and back pressure valve

Metering system Ammonia dosing devicefor the low-odour and safe handling of ammonia solution. For a stable pH value and reduced corrosion in the vapour system.

PAC Dosing Systems is the process of adding or administering an amount of PAC into a specific volume of water. It is important to be able to accurately control the ‘dose rate’ for two reasons. Firstly, to ensure there is enough PAC to provide effective treatment. Secondly, to avoid unnecessary wastage of PAC through ineffective dosing practice or spillage. Our PAC Dosing Systems solution, Trans PAC has been developed to offer a flexible, practical solution to PAC Dosing.
